PROCESS OF CLEANING WHITE LEATHER GOODS.

SPECIFICATION forming part of Letters Patent No. 776,830, dated December6, 1904. Application filed January 21, 1904;. Serial No. 189,974. "(Nospecimens.)

To all whmn it Wary concern;

Be it known that I, WILLIAM Fonenn, a citizen of the United States, anda resident of New York, county of New York, and State of New York, haveinvented certain new and useful Improvements in Processes of Cleaningand Bleaching White Leather Goods, of which the following is aspecification.

This invention relates to the process of cleaning and bleaching whiteleather goods, such as white kid gloves and the like.

The object of the invention is by an improved process to greatlydecrease the amount of time and labor heretofore expended in cleaningand bleaching articles of the character aforesaid and at the same timeto prevent all damage and shrinkage of the material, which washeretofore so apt to be incident to such a process.

In the practice of my invention for cleaning white kid gloves I firstsubject the gloves to the action of a bath composed of benzin, olcicacid, and ammonia. To prepare this bath, 1 mix the said ingredientstogether in the following proportions: Benzin, fortynine gallons andthree quarts; aqua-ammonia, 26 one pint; oleic acid, one pint. These Istir together until they are thoroughly mixed. I then allow the mixtureto rest until the water of the aqua-ammonia has settled to the bottom.This I then draw off and the remaining fluid I use for the said bath. Inthis I manipulate the gloves twice for fifteen minutes each time. In thenext place I manipulate the gloves for two minutes in a bath of benzin,oleic acid, ammonia, and alcohol. T prepare this bath, I first mixtogether two gallens of benzin,one-half of a gallon of oleic acid, andone-quarter of a gallon of aqua-ammonia, 2.6 These I thoroughly mix byagitation. I then allow the mixture to settle and then draw off thewater of the aq Lia-ammonia from the bottom. Then I add to themone-quartcr of a gallon of wood-alcohol and again agitate until all arefully mixed. While the gloves are treated with this bath the fluid ofthe first baths has been allowed to settle. l/V hen the gloves arewithdrawn from the bathof benzin, oleic acid, and alcohol, they areagain treated twice with the fluid of the lirstnamcd baths, which may beeasily poured off from any sediment it accumulated during its firstapplication. The gloves should be twice manipulated in this fiuid forlive minutes each time. Thus far the baths have been used to remove thegrease and dirt only. The gloves are bleached and further cleaned asfollows: Then I manipulate the gloves in a bath composed of benzin andchlorid of calcium, (CaOl-z.) To prepare this bath, .I mix togethertwenty gallons of benzin and three pounds of chlorid of calcium. Thevessel which is used for this bath should be such that while the benzinchlorid of calcium and the gloves are all agitated together the benzinfrom off the chlorid of calcium will pass freely to all the parts of thegloves; but the solid parts of the chlorid of calcium cannot come intocontact with the gloves. This agitation is to be continued for one-halfof an hour. If there should be any moisture or residuum of perspirationremaining in the gloves which was not removed by the former baths, thiswill effectually remove it from them. The gloves are then withdrawn fromthis last-named bath and. rinsed in clear benzin, after which they maybe dried in any approved and well-known way. The gloves will now befound to be thoroughly cleaned, very white, very pliable, and elasticand in no wise shrunk by the process.

It is evident that all kinds of leather goods. the color of which wouldnot be injured by the process and which are of such size as to to bemanipulated in the baths, may be successfully treated in this way.

Having now described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. The process of cleaning and bleaching leather goods consisting inmanipulating them twice, for the time specified in a bath composed ofbenzin, oleic acid, and ammonia, then manipulating them for the timespecified in a bath of benzin, oleic acid, ammonia, and alcohol, thenagain twice manipulating them for the time specified in the first-namedbath, then manipulating them for the time specified in a bath composedof benzin and chlorid of calcium, and lastly rinsing them in benzin,substantially herein described.

bath, then manipulating them for half an hour in a bath composed ofbenzin twenty gallons, and chlorid of calcium three pounds, and lastlyrinsing them in benzin, substantially as herein described.

In testimony that I claim the foregoing as my invention I have signed myname, in presence of two witnesses, this 141th day of J anuary, 190 i.
